vApplication led October 16, 1908. Serial No. 458,068.

To all whom it may concern.:

Be it known that we, CHARLES GILBERT IIAWLEY and ERLE K. BAKER, citizens of the 4United States, and residents of Chicago,

f pli cation to the exhaust pipes of such engines,

at points between the engine and the muHier.

The piimary object of the invention is to provide a device which may be applied to a muflier 'pipe with a minimum of labor, and which when applied, shall vbe adapted to relieve the pressure of gases in the muflier by permitting their escape before entrance Fig. 3.

thereto.

Other objects of the invention will appear .1, hereinafter.

This present invention is an improvement upon and modification of that which is shown in our copending application, Serial No. 426414-filed April 10,1908. It also preferably embodies certain of the features of the muffler cut-out disclosed in our application filedSept. 8, 1908, Serial No. 451953.

Our invention in its preferred form com'- prises a sleeve or valve body adapted to be secured upon an exhaust pipe and provided with a two ported outlet recess for communication with the'pipe and two Nvalves therefor respectively, one upon the inside and the other upony the outside of said valve body.

Our invention also consists in variousdetails of construction and in new combinations of parts, producing new and more perfect results, all as hereinafter described and particularly pointed out inthe claims.

The invention will be more readily understood by reference to the accompanying drawings forming a part of this specification,

in which:

Figure l 1s a plan vleW from beneath,I of a "v combined horn valve and muffler cut-out embodying our invention. Fig. 2 is a longitudinal section of the valve on the line XX of Fig.'3 is an end view of the valve'. Fig. 4 is a transverse vertical section, on the line Y-Y of Fig. 2, showing the deecting or gas diverting valve in open position.

Fig. 5 is a side view of the valve. Fig. 6 is a sectional view like unto Fig. 4 showing a modified'form of the valve. l

In Figs. 1 tov `5 we have shown a single device formed to be placed upon a muer pipe and adapted to perform the functions 0f a muffler cut-out or relief valve and ahornvalve. In these drawings 2 represents a portion of a muffler pipe, between the explosion engine (not shown) and the muffler (not shown). Instead of cutting thev pipe, to insert the valve, necessary' to relieve either the pressure of' gases or control and divide the flow thereof in the pi e, we sim ly make a hole 3 in the pipe and p ace the va ve on the perforated `part of the pipe. The shape of the hole in the pipe varies with different forms of our invention. It is usually `elongated and rectangular.. This. hole 3 may be made with an ordinary file and with-v out resort tomachine tools, also vwithout re-v moving the pipe from the automobile. The body of the valve is in the form of a sleeve; comprising two parts 4 and 5, having ears or lugs and clamped upon the pipe .by the screws or bolts 6. .The sleeve section 4 neednot be made to closely fit the pipe as a gas tight joint is not here required. But the joint between themember or section 5 andthe pipe must be tight and we therefore iiiterpose a suitable packing between tl1e`me1n'. ber 5 and the pipe. Said member' as clearly shown in Figs. 2.and 4, contains a packingv groove 5 and packing 7. The groove is substantially rectangular in form and the packing or gasket is. referably somewhat wider and longer than tie hole .Bin the pipe.

Compressible, fire proof `packing is used and by its'use the valve member 5 may he fitted Ato pipes of various sizes. When the two parts of the valve-body are placed on the pipe they are drawn together bylneans of the bolts 6 and in this way -the packing is.v

tightly compressed and in ade to snugly conform to the side of .thejpipe, around the opening therein.- It will be noted that the sec-tion 5 of the valve body is provided with an extension or projection 8 and that in this is a rectangular recess Qof substantially the same length and breadth as the hole 1n the l pipe. On'th'e projection is a boss 10 and inV this a threaded hole 11. A threaded nipple 12 is screwed into the hole 11 to' serve as a connection betweenv the valve and the horn (not shown) or .another pipe which' may' be interposed between the va *e and the horn roo A f ,'inuttier or outlet end of the eXhaust pipe,

The inner endifof the nipple 12 is machine finished and'forms a valve seat 13. One

.end of lthe recess 9,v that which -is distant from the inlet end of the valve (indicated by the arrow in Fig. 2) contains a valve stem or vshaft 1,4, the outer end of which is formed into an operating crank 14. communicates directly with'the recess 9 and the recess 9 as explained opens into the pi e. To normally close this passage we vemp oy the swinging or wing valve which is operated "by Vthe crank shaft or stem 14. When v. y ppened the valve swings through the opening 3 into the pipe and obstructing the same,

L with thenipple 12. 2o

serves to divert the exhaust gases from the so that. substantially thel full pressure of gas is availablein the horn or whistle connected The wing' valve' preferably comprises sev* eralv parts; namely, the member 15, having 'Y a curled end secured on the shaft 14 by rivet of the stud 16 is reduced to form the neck 1-6 which passes through a larger hole in the cen- 'ter of part 17, and is then up-set or headed,

to prevent the valve 17 from falling off. The

body of the stud is larger than the hole in valve 17 and its shoulder 16 is beveled or rounded to tightly close in the hole when the parts' are pressed against the seat. The member- 15 is. slightly narrower than the recess 9 .so that it may swing freely therein vv'and through the opening 3, and it is long '.-enough to reach across the pipe and strike the opposite wall (see dotted lines in Fig. 2 and full lines iin-Fig. 4). A spring 18, wound on the outer end of the shaft or stem 14, has,

" one-end or arm hooked over the lever 14 and the other end heldon a stud 5 on the -member 5. hold the wing of -mernber 15in closed position and hence presses the' valve part 17 against the seat 13. The bottom of the recess contains a preferably rectangular opening 19 'which merges intoa round hole 20 in a boss or projection 21 that is vv.formed on the bottom of the projection 8. The edge of the boss 21 is ground off or otherwise finished to form a (preferably) circular valve seat 22..

At each ysi'de of the valve-seat are integrallugs 23, preferably on a line that is parallel with the aXis ofthe valve body; and in perpendicular relation to such line are two other lugs 24,-24, also integral with' the remainder of member Y ,The ends of the lugs .are pref-I The nipple 12 This spring serves to normally: 42 is bored in the'pi e.

erably notched or'grooved (see Figs. 3 and 4) and are preferably ground or finished at the same time with the seat '22, being in the saine plane therewith. The ends or surfaces ofthe lugs 23 preferably stop short of the plane of the valve seat- 22. The passage deiined by the openings 19 and 2O constitutes the cutout or relief passage of the device and is iior- A 'mally closed by the tiltable' plate valve 25.

This is preferably a. dat plate which is stamped from sheet metal and itrests upon and closes tightly against the flat valve seat 22. The plate is provided with ears 25 which overlie the lugs 23, and as :the means of holding 'the plate upon the seat, we employ two bolts l26 and two compression springs 27. The bolts pass through larger holes 25 in the. plate and are screwed into thelugs 23. The ends of the springs are preferably bent out (see 27') to bridge the openings'25 andl the springs exert their pressure between the heads lof the bolts and the plate. A short extension 253 of the plate covers or bears on the outer lug 24 and --the longer extension254 covers the other lug 24 and serves as a handle by which the valve may be operated. Movement of this handle either up or down serves to tilt the plate, one

4or the other of the lugs 24 serving as the fulcrumtherefor. Tn'some cases the handle is bent downwardly and in this form it may be used as a crank to tilt the valve oiplate in other directions, the lugs 23 at such times serving as the .fulcruins This cut-out valve is readily operable by means of the usual operating pedals (not shown) and also constitutes an automatic relief or safety valve,

it being obvious that it is adapted to yield outwardly when there is an excessive pressure of gas in the exhaust pipe, as when def layed .explosions of gas occur therein.

As a means of preventing the valve body from slipping or turning on the p ipe 2 we'A employ a locking.. screw 29, preferably located in a lug 53 .on the member 5. lt is usual to remove this screw while the valve is being placed on the pipe, and when the lat ter has been properly positioned and clamped, thereon, a drill is placed inthe lug and a hole revplaced and its'en entering the hole 2', serves to securely lock thevalve upon the 1 e. p lin Fig. Gwe have illustrated a modificaf tion of our invention in which the cut-out valve is omitted; in other 'respects the device is the same asl above described. ASuch valves quired or as cut-out upon marine engines, where it is desirable to discharge. the gases outboard thiough a ipe, When the valve shown in Fig. 6 is use as arelief valve or cutout andis not -attached to a horn or other 'device requiring gas pressure, the member 15 may be shortened as 1n lsuch cases 1t 1s noty f' The screw is .then
